2(2 - 2x) = 4
Distribute (multiply) 2 inside the parentheses.
4 - 4x = 4
Subtract 4 from both sides.
-4x = 0
DIvide both sides by -4.
x = 0
x is 0 because anything divided by 0 (0/-4) equals 0.
4/3
1.3 repeating
1 1/3
These are all correct. To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one. Or just use a calculator lol.
Answer:
All real values of x such that x ≥-3
Step-by-step explanation:
g(x) = sqrt(x+3)
A sqrt must be greater than or equal to zero
sqrt (x+3) ≥ 0
Square each side
x+3≥ 0
Subtract 3 from each side
x ≥-3
The restrictions on x are x ≥-3
That means the domain is x ≥-3
All real values of x such that x ≥-3
Answer: X=31
Step-by-step explanation:
The angles are supplementary because they add up to 180 degrees. Therefore, we will make the angles equal 180 degrees using
3x+25+2x = 180
combine like terms
5x+25=180
subtract the 25 from both sides
5x=155
divide each side by 5
answer x=31
Answer:
the number of children has red or brown hair is 
.
Step-by-step explanation:
We have been given that in Marci's family there are total 6 children.
Out of 6 children
Number of children have blonde hair = 
Number of children have red hair = 
Number of children have brown hair = 
Since, we have to find the fraction of children has red or brown hair=
Hence, the number of children has red or brown hair is
